Permutation ANOVA for lmer Model

Description

This function provides permutation ANOVA for lmer model.

Usage

permanova.lmer(model, nperm = 999, ncore=3, type = c("I", "II", "III",  "1", "2", "3"),
 ...) 

Arguments

model	Model object returned by lmer.
nperm	Number of permutation, the default value is 999.
ncore	Number of core for parallel computing, the default value is 3.

Examples

# library(predictmeans)
# Oats$nitro <- factor(Oats$nitro) 
# fm <- lmer(yield ~ nitro*Variety+(1|Block/Variety), data=Oats)

## Permutation Test for model terms
# permanova.lmer(fm)
# permanova.lmer(fm, type=2)
## Compare to F test
# fm0 <- lme(yield ~ nitro*Variety, random=~1|Block/Variety, data=Oats)
# anova(fm0)
